Recent research suggests two ways of making
decisions: an intuitive and an analytical one. The current
study examines whether a secondary executive task interferes
with advantageous decision-making in the Game of
Dice Task (GDT), a decision-making task with explicit and
stable rules that taps executive functioning. One group of
participants performed the original GDT solely, two groups
performed either the GDT and a 1-back or a 2-back
working memory task as a secondary task simultaneously.
Results show that the group which performed the GDT and
the secondary task with high executive load (2-back)
decided less advantageously than the group which did not
perform a secondary executive task. These findings give
further evidence for the view that decision-making under
risky conditions taps into the rational-analytical system
which acts in a serial and not parallel way as performance
on the GDT is disturbed by a parallel task that also requires
executive resources.
